Toward the end of January I got a notification that a firmware update was available for my Samsung Galaxy Ace 2 so I went ahead and applied it.
Now my years of supporting PCs has taught me that when upgrading an OS its sometimes best to do a clean install, equally, if you have a corrupt download it’s best to delete the file before attempting to download it again.
Why I was under the illusion this didn’t apply to smartphones I don’t know.Since applying the update I’ve had quite a few crashes of applications and Android processes such as System UI and just general sluggishness.
I’ve tried uninstalling and reinstalling applications and clearing caches but to no avail.
Anyway this morning the phone just completely froze so I ended up pulling the battery.
I’ve held off a factory reset because of having to put stuff like the home Wi-Fi passphrase back in but I decided to just go ahead and do a reset and hey presto its working like new again, in fact the touchscreen appears even more responsive than when it was new.
